3000gsk vs.4000gsk
 

what i'm wondering is if i don't get valve springs and i get the 4000gsk,i've heard not to turn over 3200 rpm's how hard is it not to do?and if i get the 3000gsk,won't that give me close enough being able to turn 3000 rpm's,whats another 200?and mine when it gets wound out it pauses as it shifts like it wants another few rpm's before it shifts,will the kit fix this?

the 3000 kits is more than most would ever need

Ok. i have the 4000 kit. I can feel a big difference in the low end as well as the top end. the 4000 fuels much harder and you have to be an asshole to go over 3200. you don't need it till you have the mods for it, and the hd valve springs. If you hammer your stuff with no care in the world then i would say do the 3000 until you get the 60lb sprrings. if you can moniter your foot control. you will have no problem and you can have the 4000 before the 60lb springs. you might as well not waste your time putting in the 3000, cause your just going to want the 4000 in a few weeks of driving. It's really all up to you. the 4000 is way better, you can feel the differnce from low end to top. I really never go to 3000 rpm with it anyway. only when i am racing someone. but i have the 4000. i coulnt see reving that high with the mods i have. it would be starving for fuel. Good luck, its a fun instal and you will like it. TAKE YOUR TIME

Go with the 4Ks and be done.

i have the 4k but hardly ever go over 2200rpm

im like him ^^^ but occasionally ill go to about 3... ive got 4ks btw

I dont even know if I have springs but I go to 2800-3k often.

you have atleats 3k if your going that high with stock springs you cant turn more than 2500rpm, atleast mine wouldnt

im pretty sure my motor doesnt have any gsk upgrades and mine will turn 3 no prob.

your motor dont have springs anyway there in your fuel pump, thats wierd thow since there designed to defuel at 2200rpm with stock springs

thats what i thought.
i got a 5 speed and i can take her past 3000 no prob.
i dont like too but i can

In Gear???? Because it should defuel. If your reving past 2500 with stock springs your just makeing noise and not power. Thats why you put the Govener springs in to make power past that point

Im an expert at putting the set up in now that i have done to 2 times, its slick and not hars @ all. Im putting a set in my friends truck this thursday, so if you need any help or get hung up PM me and i will help best i can

they are easy to do thats a fact but i havent seen any trucks around hear stock that turn 3k with stock springs and not have issues

You need fuel and more timing to turn much over 3K plus

along with valve springs and more air

I HAD A 3K IN MY 12VER WISH I WOULD HAVE PUT THE 4K IN :humm:

First things first Dave lol

i have stock springs it will turn 3K but after 2500 it has no where near what it had around 1800. just my advise buy the 4k gsk. ( go big or go home).

hey guys
do you think i should get my timing turned up?
i have a 96 12v #10 fuel plate and star wheel cranked with boost elbow

yes keep it under 16* till you get head studs

kk
about how much does it cost to do it?
what will really be a benefit?

your truck will run and perform better don't know how much a shop will charge to do it but the tools are arround 200 bucks

ok, well im new here, and my current ride is a yz125 haha but im getting my dads 96 12v in about a year. so right now it will go to like 2600 in nuetral, and in drive like 2250 or so. so if i got the 3k gsk its only gonna go to like 2600 in drive right? but if i got the 4k its not going to go past 3200 anyway without changing the shift points on the tranny? is this right, it seems from what ive heard that its right.

yes and no, the truck will hit 4k without any tranny work, the reason not to exceed 3200rpm is because you will float vavles without 60lb valve springs. with a 3k kit you should be able to hit2800rpm before defueling starts.

i have noticed installing springs is way more efective in 5speed 215 pumps over the auto 180 pump. i just put a 3gsk in my buddies white 97 5speed and the thing bakes tires into 4th gear and boots on the high way. i was jelous of his truck after the install.

i didnt notice any difference at all in my 175 pump and the current 215 pump, im running the same dvs, plate, afce and springs and really see no difference other than a tad more fuel

That would be from the 215 pump....

wat exactly are these kits for? could i put one on my 94 auto cummins or is it hard on the tranni? just want the run down on it

its the governor springs, it lets the truck rev higher...3000 is good 4000 is better in the long run for most people...but once you get above 3200 RPMS you will float your valves...and yes you can put them in your truck...it should really hurt your tranny i just lets the truck fuel longer in the top end:U:

how is a kit like this good for it if it red lines at 3000?

Thats wierd.....How did you instal them? are you sure you got all the shims out? You need to make sure you measure properly too. I set them @ .071 and made sure they were the same. I have the 4000gsk in my truck and the stupid 3000gsk hammers down in that 5speed compared to my auto....But he does have a 0 plate and the 215 pump so im sure thats why his goes better than mine. :argh:

Its red line is 3000 With a stock pump. Once you upgrade your pump to push more fuel, then you can turn more rpms ans still be making power. Your truck will perform much better with the springs and even better if you advance your timming....so i hear, but i have not done it yet... thats next

If I remember correctly it has been noted to run at least a #10 plate to see great results. The gov spring kit doesn't work as well with a #11. Again if I remeber correctly.
